Emulators

QLay is a set of QDOS QL emulators for DOS, Windows and Linux by Jan Venema of The Netherlands. This is a freely distributable emulator with no restrictions. You can download the most recent versions from Jan's Web site: http://web.inter.nl.net/hcc/A.Jaw.Venema

QPC1 is a QL emulator using SMSQ/E running in DOS. This version has a few limitations as described in the documentation files in its folder. Support etc from Marcel Kilgus and Jochen Merz Software, both of whose internet addresses are listed under QPC2 below. QPC2 is a QL emulator using SMSQ/E running on Windows 95/98/NT machines. This is a demo version of a commercial product written by Marcel Kilgus, available from Jochen Merz Software in Germany. It needs a minimum of a 486 processor. There are some restrictions on this version - see the documentation (mostly that you cannot save files to floppy or hard disk).

QPC2v3 is a demo version of the 'colour drivers' version of QPC2, supporting 16-bit colour on suitably-equipped PC systems. The proper name for the so-called colour-drivers is Graphics Driver 2 or GD2 for short. There are some restrictions in this demo version, most notably that you cannot save files to floppy or hard disk. The full version of QPC2 has QXL.WIN file systems as well as a DOS device driver (read/write PC format floppy disks, hard drives etc) as well as a TCP/IP access system for web access and email using programs like Lynx, QPOP3 etc from Jonathan Hudson. QPC2 is a very fast emulator, which uses SBASIC which is SuperBASIC compatible (only much faster!) and can be set to use very large RAM memory.

QemuLator for Windows is also written by Daniele Terdina and is Shareware (registration of 40 dollars at the time of writing). Further details from the author's Web site at:www.terdina.net/ql/q-emulator.net. This emulator can emulate a standard QL, a Gold Card QL, or even a fast QL system with up to 16MB of RAM! It can run some versions of SMSQ/E or use QDOS ROM images (including Minerva), can access QXL.WIN or native file systems and has a built in TCP/IP system, so that you can use email and web browser programs such as those from Jonathan Hudson. The latest versions of QemuLator can also emulate Aurora 256 colour with Aurora/Gold Card version of SMSQ/E and Q60 16-bit colour displays if you write direct access code.

QDOS4Amiga is a QDOS emulator for the Commodore Amiga, by Rainer Kowallik and Mark Swift. It is freeware. Up to date copies may be obtained from most Ami-Net sites. See the README1.TXT file first

QDOS Classic for Amiga is a QL emulator for the Commodore Amiga by Mark Swift. QDOS Classic for Amiga is closely related to QDOS Classic for Q40 by the same author. Freeware. Support and download from http://www.mswift.unisonplus.net/ql/index.html

QLem is an emulator for certain Atari ST machines, by Johan Klockars. Freeware. Details from  the Ancient File Library at http://www.devili.iki.fi/pub/emulators/Sinclair/QL/. May be downloaded here as ZIP or LHA files:
qlem.zip - download QLem as zipped file (67K)
qlem.lzh - download QLem as LHA file (66K)

QDOS Classic for Q40/Q60 may be downloaded from my Q40 page, or from the official Q40 website at www.q40.de. QDOS classic, as the name implies, is an implementation of the traditional QL QDOS operating system rather than the SMSQ/E operating system. There's also a version of Linux for Q40 and Q60 - click on the link above to Claus Graf's Q40 website for further details.
